Jon Jones recently fought Glover Texiera in the Octagon and he was throwing some very suspicious kicks. Spinning back kicks, ax kicks, spinning ax kicks...etc, we're seeing some TKD in the UFC now...not just some of the techniques that TKD shares with other arts, but techniques that are uniquely TKD. It's interesting to see more and more fighters slip this into their bag of tricks. Will we see more? What else could appear? Who can pull it off?
